MIT researcher Deb Roy wanted to understand how his infant son learned language — so he wired up his house with videocameras to catch every moment (with exceptions) of his son’s life, then parsed 90,000 hours of home video to watch “gaaaa” slowly turn into “water.”

The process and results are astonishing producing data-rich research with deep implications for how we learn and also how we connect and share. Through gorgeous visuals, Roy shows new social structures and dynamics that have previously not been able to be seen to reveal how we communicate for major events and things we like… and why should we care?

Roy’s findings can offer valuable insights for the advertising world, among many other disciplines.
